            <p>今天刚花了半小时时间调了一下公司的主机，因为有线网络一直连接不上，一气之下找了一个无线网卡直接怼上试试，结果因为是Ubuntu系统还不适配，哎，只好耐心找了下驱动，费了些时间搞定了，在这简单记录下。</p>

<p>参考<a href="https://blog.csdn.net/daxus/article/details/84348308">博客</a><br>
<a href="https://github.com/whitebatman2/rtl8821CU">驱动链接</a></p>
<p>如何识别是不是TP-LINK 5500, 两个办法：<br>
第一是查看USB口上有小字标识，写着驱动型号；<br>
第二是<code>lsusb</code>命令，看有没有<code>1a2b</code>的驱动参数，如果有说明是的</p>
<p>TP-LINK 5500的网卡驱动是8821cu。</p>
<p>下载完成后，按照下面步骤依次输入命令即可：</p>
<pre><code class="language-shell">make
sudo make install
sudo modprobe 8821cu
</code></pre>
<p>最后输入该命令即可</p>
<pre><code class="language-shell">sudo usb_modeswitch -KW -v 0bda -p 1a2b
</code></pre>
